Server talking, talking server talk… reprise… (1)

After getting our Tomcat5 / IIS6 installation up and running, we’ve noticed that we’re having a high CPU utilization; for 90% of the time the tomcat process is hitting %99 CPU usage. This is a bit of an issue as we aren’t planning “single server, single process”… So, we’re now doing some testing – to see

1) if we can replicate the issue

2) if we can make a solution(proposed solutions so far – use Apache in front – don’t use any web server in front of Tomcat … )

The process:

1) download tomcat, java et al.2) Install it :)

This time around (it’s hardly been a month) and the java version is now jdk1.6.0_06.

Java is installed to c:\java\jdk1.6.0_6 and C:\Java\jre1.6.0_06\(no netbeans this time around – I don’t think they’re actually needed for what we want to do)

The Tomcat version is still apache-tomcat-5.5.26 (much slower turn-around?)

Tomcat is installed to C:\Apache\Tomcat_5.5

runtime is set to point to c:\java\jre1.6.0_06

Reading through tomcat notes (that I might have previously missed); Tomcat no-longer needs the full java jdk/sdk ( a mental note to be made, to myself, for future installations)

It looks like there are issues with JNI (Genie?) applications – I wonder if that could be causing some of the problems we’ve been having… -ponders-

Odd; we seem unable to access the server … I wonder if someone’s blocking 8080 on the firewall… ponders… oh well, it’ll wait until next week now
